In all my infinite computer-savvy wisdom I might've accidentally deleted my "Purchased" playlist in iTunes the other day. I'm happy to report that indeed, you are able to delete the playlist with all your personalized purchased music history deets.
On the flipside, getting it back isn't neeeeearly as fun as deleting that massive sucker. Yeah, this stuff happens.
Not to worry, file this handy Sopheava guide away in your back pocket for that Tuesday morning when you're flying out the door and need your purchased playlist back RIGHT NOW.
Ok, the purchased playlist is back. Putting all your music back on that playlist can be a massive PITA if your music collection is anywhere in the realm of the size of mine. Never fear, iTunes developed the least intuitive, most mislabled tools for your n00b disposal.
L'voila!
